工作原理

顎式破碎機在工作過程中由電動機驅(qū)動皮帶和皮帶輪，通過偏心軸使動顎上下運動，當(dāng)動顎下行時，定顎與動顎間夾角變小，物料被壓碎達到破碎目的；當(dāng)動顎上升時，定顎和動顎間夾角變大，動顎板在拉桿、彈簧的作用下離開定顎板，此時已破碎物料從破碎腔下口排出。

結(jié)構(gòu)概述

破碎機主要有機體、偏心軸、靜顎、動顎、調(diào)整裝置、傳動裝置、動力部分等組成。

機體采用兩種結(jié)構(gòu)形式，整體鑄造型和好的鋼板焊接型，并由多條加強筋組成整體箱體。偏心軸由好的碳結(jié)鋼制成，并車制成偏心。兩端裝有軸承并緊固在機架上。動顎有整體鑄造和焊接結(jié)構(gòu)兩種形式。動顎和機架上固定有一對ZGMn13鑄成的顎板。當(dāng)電機帶動皮帶輪、并通過偏心軸驅(qū)動動顎進行往返運動時，由顎板將物料壓碎，達到破碎的目的。

偏心軸上裝有皮帶輪，電動機的動力通過三角皮帶傳遞，使機器工作。另一端裝有飛輪，它可以積蓄動力，增加破碎力度。大型機還鑄造有偏心塊，使機器運轉(zhuǎn)到破碎點時，偏心塊積蓄的動能釋放出來，增加破碎力度。

調(diào)整裝置主要用來調(diào)整排料口的大小的，大小與產(chǎn)量成正比，改變撐板位置，料口間隙就能得到調(diào)整。實驗室用小型機調(diào)節(jié)裝置裝在機器后部，松開滾花螺栓，轉(zhuǎn)動手輪進行調(diào)整，順時針出料粒度小，反之粒度大。大型機型靠多層墊板的加減進行調(diào)整。撐板系統(tǒng)不但能調(diào)整間隙，還能起到保障作用，喂料超載時，或遇到鐵器時，它會彎曲或折斷，使機器停止工作，保護其他零件不被破壞。為了保護機架長期使用，在機架的兩邊裝有護板，以保護機體不被磨損。

安裝試車

機器須安裝在避雨的地方，盡可不露天安裝。

電機須安裝在破碎機的后方，機器有四條地腳螺絲固定在混凝土地基上，地基要留出排料口，其斜度不小于50度。

實驗用的小型破碎機可以不打地基，也不用考慮排料，但要放在平整的地面或工作臺上，并墊一層5毫米左右的橡膠板，以達到平穩(wěn)和減震的作用。

破碎機與其他設(shè)備配合使用，須從方便生產(chǎn)、有利作業(yè)等方面統(tǒng)籌安排。

破碎機安裝完畢，并超過地基凝固期后，方可進行試車。試車前再檢查一遍所有螺絲是否擰緊，各連接零件是否可以接觸。然后先用人力轉(zhuǎn)動皮帶輪，確認為運動不受阻礙時，即可進行空車試驗，空車試驗兩小時后，觀察機器無沖擊、無噪音，密封處無漏油，皮帶輪和飛輪無擺動。機件無松動等現(xiàn)象，軸承溫升不超過65℃。若發(fā)現(xiàn)以上故障，必須立即停車進行檢修。確認破碎機試運轉(zhuǎn)正常后，即可進行負荷試車。采用次硬度或小塊度物料進行工作，如無故障,即可進行正常生產(chǎn)。五、使用維護及注意事項破碎機必須在空載下啟動。啟動前仔細檢查各部件的緊固情況、彈簧的彈性情況、皮帶的松緊情況。

出料粒度的調(diào)整：可將機器后端調(diào)整手柄鎖緊螺釘松開，順時針為調(diào)小，反之則大。可同時觀察顎板的間隙,調(diào)整合適的間隙后，要人工轉(zhuǎn)動機器轉(zhuǎn)夠兩轉(zhuǎn)以上，方可啟動電機進行工作。不允許調(diào)整間隙后直接啟動電機進入工作。

當(dāng)破碎顎板磨損嚴(yán)重，無法使用時，可將顎板顛倒過來，可以繼續(xù)使用。

為了保證機器長期良好使用，對各活動機構(gòu)及軸承內(nèi)經(jīng)常加注鈣基脂，撐板與滑塊、撐板與動顎支點每15天加油一次、各軸承內(nèi)每30天加油一次。

破碎機啟動后運轉(zhuǎn)速度達到正常速度后，方可喂料，無料斗的機器，加料應(yīng)從正前加入，不需從側(cè)面加入，以防止機器過載和顎板偏斜造成事故。并嚴(yán)格防止鋼鐵，超硬度巖石進入機器，以免損壞機件。

每班啟動時，要仔細檢查破碎機的齒板是否松動，工作中要經(jīng)常性地觀察檢查齒板的工作情況，發(fā)現(xiàn)異常情況時，要停止工作，徹底處理并排除故障，防止齒板的松動或位移而擠壞機器。運轉(zhuǎn)時，嚴(yán)禁任何清理工作和安裝撤卸皮帶，禁止用手或撬桿從裝料口內(nèi)取出礦石，或移動大塊礦石的位置，防止事故發(fā)生。停車之前，必須先停止給機器供料，待機器內(nèi)的物料全部吐出完后，方可停車。

破碎機用三角皮帶傳動，要經(jīng)常檢查皮帶的使用情況，如其中30%皮帶損壞嚴(yán)重，就必須全部換新的三角帶，不可新舊混用，已免減少功率，影響生產(chǎn)效率。

破碎機每年進行一次撤機保養(yǎng)。每兩年進行一次大修。

PE JawCruasherLong-term supply of ore JawCruasherPEX250×1000

Jaw cruashers are widely used in mining, buildingmaterials, chemical, metallurgical, and other industri are capableof performing coarse and medium cruashing operations on various ores, rocks, andother materials with a compressive strength not exceeding320MPa.

Scope of Appli

The sealed jaw cruasher is primarily used for medium and finecruashing of ores, coal, or other medium-strengthmaterials. Its cruashing method is a reciprocating compressiontype, re on two wear-resistant jaw a plates to cruash the material. The material to becruashed should be brittle; the shape of thecruashed material is mostly flaky, and thecompressive strthe material does not exceed 80MPa. If the moisturecontent of the material exceeds 8%, the discharge will beobstructed.

This machine features a reasonable design,easymaintenance, and simple operation. It is characterized by alarge cruashing ratio, uniform particle size, simpleadjustment, convenient discharge, and low dust due to full sealing.With advanced structurenable design, stable operation, lowvibration, and low noise, it is widely used in metallurgy, mining,coal, coking, and other industries.

The small modelforcruashingand sample preparation in laboratories. It is fully sealed with nodust leakage. Voltage options are 380V or 220V.

Working Principle

Durig operation, the jawcruasher is driven by an electric motor throughbelts and pulleys. The eccentric shaft causes the movable jaw tomove up and down. When the movable jaw moves dd, the angle betweenthe fixed jaw and the movable jaw decreases,cruashing the material to achieve thecruashing purpose. When the movable jaw movesupward, the angle between the fixed jaw and theaw increases. Underthe action of tie rodas and springs, the movable jawa plate moves away from the fixed jawa plate, and the cruashed material is discharged from the loweroutlet of the crusg chamber.

Structural Overview

The cruasher mainly consists of the frame, eccentricshaft, fixed jaw, movable jaw, adjustment device, transmissiondevice, and power section.

The framo structural forms: integral castingand high- steel a plate welding, composed of multiple reinforcingribs to form an integral box structure. The eccentric shaft is madeof high- carbon structureel and machined into an eccentricshape. Bearings are installed at both ends and fixed to the frame.The movable jaw has two forms: integral casting and weldedstructure. A pair o a plates made of ZGMn13 are fixed on the movable jawand the frame. When the motor drives the pulley and the eccentricshaft drives the movable jaw to procate, the material iscruashed by the jaw a plates to achieve the cruashing purpose.

A pulley is installed on the eccentric shaft,and the power of the motor is transmitted thro a V-belt to make themachine work. A flywheel is installed at the other end, which canaccumulate power and increase cruashing force. Large machines are also cast witheccentric blocks, hat when the machine runs to thecruashing point, the kinetic energy accumulated bythe eccentric blocks is released to increase thecruashing force.

The adjustment device is mainly used toadjust the size of targe opening. The size is directly proportionalto the output. By changing the position of the togglea plate, the discharge gap can be adjusted. Theadjustment device of the small laboratory machine installed at therear of the machine; loosen the knurled bolt and turn the handwheelto adjust. Clockwise rotation results in smaller discharge particlesize, and vice versa. e models are adjusted by adding or removingmultiple layers of shims. The toggle a plate system not onlay adjusts the gap but also serves as a safetydevice. When the feeding is overloaded ounters metal objects, itwill bend or break, stopping the machine to protect other partsfrom damage. To protect the frame for long-term use,guard a plates are installed on both of the frame toprotect the body from wear.

Installation and Trial Run

The machine must be installed in a shelteredplace, abvoiding open-air tallation as much aspossible.

The motor must be installed behind thecruasher. The machine is fixed to a concretefoundation with four anchor bolts. The foundation must reserve adischarge outlet h a slope of not less than 50degrees.

For small laboratorycruashers, a foundation is not required, anddischarge considerations can be ignored; however, it must be placedon lat floor or workbench, and a rubber sheet about 5mm thickshould be placed underneath to ensure stability and reducevibration.

When the cruasher is used in conjunction with othere, overall gements must be made considering productionconvenience and operational efficiency.

Trial run can onlay be conducted after the installation iscompleted and the foundation curing period has passed. Before thetrial ruk all screws again to ensure they are tightened and thatall connecting parts are in reliable contaect. Then, manually rotate the pulley toconfirm there is no obstruction before conducting the n test. Aftertwo hours of no-load testing, observe that the machine has noimpact, no noise, no oil leakage at seals, and no wobbling of thepulley nd flywheel. Check for no loose parts, and ensure thebearing temperature rise does not exceed 65°C. Ifany of the above faults are found, the machine must be stopped immmaintenance. After confirming the cruasher runs normally during the trial run, loadtesting can be conducted. Use materials of medium hardness or smallsize for operation; if there are no fal production cancommence.

V. Operation, Maintenance, andPrecautions

The cruasher must be started under no-load conditions.Before starting, carefully check the fastening of allponents, theelasticity of the springs, and the tension of thebelt.

Adjustment of discharge particle size: Loosenthe locking screw of the adjusting handle at the rear of the machngclockwise reduces the size, and vice versa. The gap between thejaw a plates can be observed simultaneously. Afteradjusting to the appropriate gap, manually rotate the machine forat least two full turns before starting the motor. It is absolutelyforbidden to start the motor directly after adjusting thegap.

When the cruashing jaw a plate is severely worn and cannot be used, it canreversed to continue use.

To ensure long-term good operation of themachine, fre add calcium-based grease to all movingmechanisms and bearings. Lubricate the togglea plate and sli, as well as the togglea plate and moving jaw pivot, every 15 days;lubricate the bearings every 30 days.

After the cruasher starts and reaches normal speed, feedigcan begin. For machines without a hopper, material must be addedfrom the front center, not from the side, to prevent machineoverload and jaw a plate skewing, which could causents. Strictlyprevent steel and super-hard rocks from entering the machineto abvoid damaging parts.

At the start of each shift, carefully checkif the tooth a plate is loose. During operationntly observe theworking condition of the tooth a plate. If any abnormality is found, stop themachine, thoroughly handle the issue, and eliminate the fault toprevent the tooth a plate frloosening or shifting and damaging themachine. During operation, any cleaning work or beltinstallation/removal is strictly prohibited. Do not use hands orpry bars to remove ore or move largeces from the feed opening toprevent accidents. Before stopping the machine, feeding must bestopped first, and the machine must be allowed to discharge allmaterial before shutting down.

The crus uses V-belt transmission. Thecondition of the belts must be checked fre. If 30% of thebelts are severely damaged, all V-belts must be replaced with nnes;new and old belts must not be mixed to abvoid reduced power and decreased productionefficiency.
